  • FIG. 6 is a schematic folded view of the foldable shelf of the rack assembly as shown in FIG. 5.
    •  DETAILED DESCRIPTION OF THE INVENTION
  • Referring to the drawings and initially to FIGS. 1-4, a rack assembly in accordance with the preferred embodiment of the present invention comprises a framework 2, and a foldable shelf 1 mounted on the framework 2.
  • The foldable shelf 1 includes a support plate 10 attached to the framework 2, an adjustable panel 12 pivotally connected with the support plate 10, and a plurality of support legs 14 pivotally mounted on the adjustable panel 12.
  • The adjustable panel 12 of the foldable shelf 1 is pivotally connected with the support plate 10 by a plurality of hinges 121. The adjustable panel 12 of the foldable shelf 1 has a bottom provided with a plurality of mounting brackets 13. Each of the mounting brackets 13 of the adjustable panel 12 has a substantially inverted U-shaped profile and has an inner portion formed with a receiving space 131.
  • Each of the support legs 14 of the foldable shelf 1 has an upper end provided with a pivot portion 141 pivotally mounted on a respective one of the mounting brackets 13 of the adjustable panel 12. The pivot portion 141 of each of the support legs 14 is pivotally connected with the respective mounting bracket 13 of the adjustable panel 12 by one of a plurality of pivot shafts 15. The pivot portion 141 of each of the support legs 14 is movable in the receiving space 131 of the respective mounting bracket 13.
  • In practice, the adjustable panel 12 is movable relative to the support plate 10 between a first position as shown in FIG. 2 where the adjustable panel 12 is perpendicular to the support plate 10 so as to expand the foldable shelf 1 and a second position as shown in FIG. 6 where the adjustable panel 12 is parallel with and rests on the support plate 10 so as to fold the foldable shelf 1. In addition, each of the support legs 14 is movable relative to the adjustable panel 12 between a first position as shown in FIG. 2 where each of the support legs 14 is perpendicular to the adjustable panel 12 so as to expand each of the support legs 14 and a second position as shown in FIG. 5 where each of the support legs 14 is parallel with and rests on the adjustable panel 12 so as to fold each of the support legs 14.
  • In operation, referring to FIGS. 2-6 with reference to FIG. 1, the adjustable panel 12 initially abuts the support plate 10 as shown in FIG. 6. Then, the adjustable panel 12 is pulled outward relative to the support plate 10 so that the adjustable panel 12 is perpendicular to the support plate 10 as shown in FIG. 5. Then, each of the support legs 14 is pulled outward relative to the adjustable panel 12 so that each of the support legs 14 is perpendicular to the adjustable panel 12 as shown in FIG. 2. Thus, the adjustable panel 12 is pulled and extended outward from the support plate 10 so as to expand the foldable shelf 1 as shown in FIG. 1 for use with a user.
  • On the contrary, when the user wishes to fold the foldable shelf 1, each of the support legs 14 is pushed toward the adjustable panel 12 so that each of the support legs 14 is moved to abut the adjustable panel 12 as shown in FIG. 5. Then, the adjustable panel 12 is pushed toward the support plate 10 so that the adjustable panel 12 is moved to abut the support plate 10 as shown in FIG. 6. Thus, the adjustable panel 12 is folded onto the support plate 10 so as to fold the foldable shelf 1 as shown in FIG. 6 when not in use.
  • Accordingly, the foldable shelf 1 is expanded outward for use with a user and is folded when not in use so as to enhance the versatility of the rack assembly. In addition, the foldable shelf 1 can be folded when not in use so as to reduce the whole volume of the rack assembly, thereby decreasing the cost in packaging, transportation and storage of the rack assembly. Further, the foldable shelf 1 can be expanded and folded easily and quickly, thereby greatly facilitating the user expanding and collapsing the foldable shelf 1.
  • Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
